Budapest Drinking Water Supply Threatened by Record Low Danube Levels

Hungary is experiencing a significant drop in Danube water levels, with about 80 million m³ less water arriving each day than usual. The reduced river flow lowers pressure on the river‑bed filtration system that feeds the so‑called "csápos wells" on Szentendre Island and Csepel Island, which supply Budapest’s drinking water.

If the Danube’s level falls far enough, the pressure decrease could sharply cut the amount of water reaching these wells, potentially halting production entirely. Several villages around Budapest are already facing water shortages, and the drought is causing lakes, streams and smaller rivers to dry up, creating ecological damage.

Authorities warn that the capital’s water security now depends on maintaining sufficient river levels, highlighting the broader risk to urban water supply amid the ongoing drought.
